Flash Flood Warning Extended; Practice Caution in Heavy Rain

The National Weather Service (NWS), Weather Forecast Office Guam has issued a flash flood warning for Northeastern Guam until 1:15 p.m. this afternoon. Between 1 and 3 inches of rain has fallen. Additional rainfall amounts of 1 to 3 inches is possible. Flash flooding is ongoing or expected to begin shortly. 

Some locations that will experience flash flooding include Dededo, Tamuning, Yigo, Mangilao, Chalan Pago-Ordot, Barrigada, Hagatna Heights, Andersen AFB, Mongmong-Toto-Maite, Sinajana, and Asan.

Polaris Pt., Piti, both north and southbound lanes are reported impassable at this time. Motorists are advised to seek alternate routes.

Residents and visitors are advised to take the following precautionary actions:
  • If driving, be alert for low visibilities and slippery roads in heavy rain;
  • Slow down where water is ponding on the road;
  • Turn Around, Don’t Drown. Avoid walking or driving through flood waters. Just 6 inches of moving water can knock you down, and 2 feet of water can sweep your vehicle away;
  • Do not camp, park, or hike along streams, rivers, and creeks during heavy rainfall. These areas can flood quickly and with little warning.

The Offices of Guam Homeland Security and Civil Defense (GHS/OCD) remind the community to practice caution while traveling in heavy rain, driving below the speed limit and allowing enough braking distance between vehicles.
